6 Types of Overlock Stitches Overlock stitches are classified in a number of ways. The most basic classification is by the number of threads used in the stitch. Industrial overlock machines are generally made in 1, 2, 3, 4, or 5 thread formations. Each of these formations has unique uses and benefits: 1-thread formations are used for end-to-end seaming, or butt-seaming. Two- and three-thread formations, also known as merrowing, are the most common, used for edging and seaming, especially on knits and wovens. Four-thread formations are called mock safety stitches and create extra strength while retaining flexibility. 5-thread formations, which utilize 2 needles, are called safety stitches, creating a very strong seam used for apparel manufacturing. Overlocking is also referred to as overedging, merrowing or serging. Though serging technically refers to overlocking with cutters, in practice the four terms are used Merrow rolled blanket stich Narrow blanket Stitch 3-thread, ¼ wide, 7 stitches per inch Traditional Blanket Stitch 2-thread, 1/8 wide, 20 stitches per inch, with differential feed: Photo: Merrow 4-thread, 5/32 wide, 17 stitches per inch Photo: Merrow Sewing Machine Company Purl Stich, Photo: Merrow Sewing Machine Company Merrow blanket Stitch 4-thread, 5/32 wide, 17 stitches per inch, Photo: Merrow
